Description

Audio Wireless AD224 4-way Antenna Distribution System

Audio Wireless AD224 — Custom designed 4-way antenna distribution system for diversity receivers for portable sound bags. The AD224 is a 2-IN and 2×4 OUT active antenna distribution system with in-built high selectivity, very low insertion loss band-pass filters. The AD224 eliminates multiple receiver antennas and provides a tidy sound bag solution with improved RF performance. Advanced filtering design cleans up dirty RF within the selected bandwidth before feeding into the Diversity Receivers this is very important in crowded radio frequency spectrum to protect the receivers from unwanted RF signals.

FEATURES

• One pair of antennae feeds up to four diversity receivers
• Built-in band-pass filtering and signal splitters
• Remote antenna powering
• User-adjustable system gain
• Industry standard connectors
• Intuitive TFT display menu and LED indicators
• Master ON-OFF switch
• Continuous system Voltmeter
• Soft ON/OFF switch for each individual Remote Antenna powering
• CNC machined aluminum custom design, lightweight and rugged – fits neatly in any sound bag

PRODUCT OVERVIEW

The AD224 is designed for where the weight and size matters without sacrificing on performance. The antenna inputs are BNC connectors, which enables use of standard low loss RF coaxial extension cables, and the outputs are 2 x 4 mini-RF SMA connectors feeding the diversity receivers.

In applications when remote antenna powering is needed, the AD offers switchable Active Antenna Powering with RED LEDs indicating power ON/OFF status, the Active Antenna Powering can be turned ON/OFF through the high visibility large display menu.

The AD224 has a very high input signal handling capacity with very low noise figure and offers an outstanding inter-modulation performance when compared to other low power devices available.

The tuning bandwidth is custom tuned with a semi broadband response to suit varying applications; the system RF gain is user adjustable in 1dB steps between +6dB to -10dB, the AD224 is compatible with full-digital, digital-hybrid and analogue radio microphone receivers available in the industry.

The AD is externally powered between 10-18Vdc, the DC input connector is an industry standard 4-pin Hirose connector. The inbuilt Voltmeter continuously displays dc input voltage status.

Audio Wireless Antenna Distribution (AD) and Antenna Combiner (AC) and digitally tuned systems are now first choice among freelance sound engineers, hiring companies as well as major broadcasters for all wireless microphone applications.
